Power couple Beyoncé and Jay-Z joined super-producer Pharrell to celebrate the 10th anniversary of his Billionaire Boys Club clothing line at Tribeca Canvas in New York City on Tuesday night. B rocked a Billionaire Girls Club sweater while posing with Jay and Pharrell. They sat down to toast the occasion at an intimate dinner presented by HTC.

Jay-Z partnered with Pharrell on BBC in 2011. As part of the deal, Rocawear handles the manufacturing and distribution of the line.

The Roc Nation mogul is about to close a $20 million deal with Samsung Mobile, reports Page Six. “The eight-figure deal will be inked in the next few weeks, and is the biggest of its kind,” said the source. “You can speculate that he’ll want to develop some kind of new music-streaming service to promote his acts and music on mobile devices.”
